Installing Batteries
With LEGO
®
MINDSTORMS
®
Education EV3, you have the choice of
using normal AA batteries or the EV3 Rechargeable Battery pack
included in the LEGO MINDSTORMS Education EV3 Core Set. If you
experiment with both, you will find that each option has characteristics
to consider when constructing your robots. For instance, six AA
batteries weigh more than the Rechargeable Battery, and the EV3 Brick
with the Rechargeable Battery installed is slightly larger than the
EV3 Brick with six AA batteries.
The EV3 Rechargeable Battery is a convenient and economical
alternative to using AA batteries. It can be recharged while inbuilt
in a model, saving you the trouble of disassembling and reassembling
a robot to replace batteries.
To install the Rechargeable Battery on the EV3 Brick, remove the
battery cover on the back of the EV3 Brick by pressing the two
plastic tabs on the side. If there are batteries in the EV3 Brick,
remove them. Insert the Rechargeable Battery in the slots that held
the battery cover in place and snap the battery in place. The battery
cover is not used.
If it is your first use of the battery – or if the battery is completely
drained, let the battery and the EV3 Brick charge together for at
least twenty minutes.
Using the enclosed power adaptor cord, connect the Rechargeable
Battery to a wall outlet. Make sure to keep the transformer cord and
battery where they will not be tripped over or get wet.
When you plug the uncharged battery into a wall socket, a red
indicator light will be lit. When charging is complete, the red light
will go out and the green light will be illuminated. The recharging
process will generally take three to four hours. If you use the EV3
Brick while the battery is charging, it will take longer. Before you
start to use the Rechargeable Battery for the first time, it is
recommended that it is fully charged.
